Operating Water Cherenkov Detectors in high altitude sites for the Large Aperture GRB Observatory (2009)

Allard, D., Alvarez, C., Asorey, H., Barros, H., Bertou, X., Castillo, M., ...

Water Cherenkov Detectors (WCD) are efficient detectors for detecting GRBs in the 10 GeV - 1 TeV energy range using the single particle technique, given their sensitivity to low energy secondary...

The Large Aperture GRB Observatory (2009)

Allard, D., Alvarez, C., Asorey, H., Barros, H., Bertou, X., Castillo, M., ...

The Large Aperture GRB Observatory (LAGO) is aiming at the detection of the high energy (around 100 GeV) component of Gamma Ray Bursts, using the single particle technique in arrays of Water...

Water Cherenkov Detectors response to a Gamma Ray Burst in the Large Aperture GRB Observatory (2009)

Allard, D., Alvarez, C., Asorey, H., Barros, H., Bertou, X., Castillo, M., ...

In order to characterise the behaviour of Water Cherenkov Detectors (WCD) under a sudden increase of 1 GeV - 1 TeV background photons from a Gamma Ray Burst (GRB), simulations were conducted and...

Interactions of UHE cosmic ray nuclei with radiation during acceleration: consequences on the spectrum and composition (2009)

In this paper, we study the diffusive shock acceleration of cosmic-ray protons and nuclei, taking into account all the relevant interaction processes with photon backgrounds. We investigate how the...

Detecting gamma-ray bursts with the Pierre Auger Observatory using the single particle technique (2005)

Allard, D., Parizot, E., Bertou, X., Beatty, J., Vernois, M. Du, Nitz, D., ...

During the past ten years, gamma-ray bursts (GRB) have been extensively studied in the keV-MeV energy range but the high energy emission still remain mysterious. Ground based observatories have the...

The Compton trail of gamma-ray bursts: A long-after glow (2004)

Allard, D., Parizot, E.

As they travel through the gas of the host galaxy, some of the gamma-rays emitted in a Gamma-Ray Burst (GRB) may experience Compton scattering and reach an observer even if he is not located in the...
